The normal body temperature of a newborn is the baby’s internal temperature, between 36 degrees – 37 degrees, because the baby’s internal temperature is not easy to measure, now commonly used oral temperature, anal temperature, axillary temperature to represent, different parts of the measurement standards vary. Oral temperature measurement: usually with the mercury storage tank end of the thermometer, tilted placed in the baby’s sublingual tropics, keep the length of 3 minutes, the standard value of the normal body temperature of newborns: 36.3 degrees – 37.2 degrees. Anal temperature measurement: usually the anal table is slowly inserted into the baby’s anus 3cm-4cm, keep measuring for 3 minutes, the normal body temperature value of newborns: 36.5 degrees – 37.7 degrees. Axillary temperature measurement: usually the thermometer is placed in the baby’s armpit area, close to the skin, preferably using the flexed arm over the chest posture, clamping the thermometer and keep measuring for 10 minutes, the normal temperature value of newborns: 36 degrees – 37 degrees. If there is more than one degree, it can be considered a fever phenomenon, where hypothermia means that the body temperature is lower than 38 degrees, and hyperthermia is a body temperature of more than 39 degrees. The normal body temperature of newborns is between 36 degrees and 37 degrees. Parents should check the temperature of their newborns every day, and if there are obvious abnormalities, in order to avoid the condition becoming more serious, they must be examined in time, so as to protect the health of their newborns.
